## Abstract Chitosan and poly(vinyl alcohol) blend fibers were prepared by spinning their solution through a viscoseβtype spinneret at 25Β°C into a coagulating bath containing aqueous NaOH and ethanol. The influence of coagulation solution composition on the spinning performance was discussed, and t
## Abstract Blend microspheres of chitosan (CS) with poly(vinyl alcohol) (PVA) were prepared as candidates for oral delivery system. CS/PVA microspheres containing salicylic acid (SA), as a model drug, were obtained using the coacervationβphase separation method, induced by addition of a nonsolvent
